I know this has been asked before, but I wanted to get thoughts: we just recieved our first wedding gift in the mail(!). FI and I want to wait and bring it to our shower, which is in a few weeks, but I'm wondering if we should open it sooner so that we can get a thank you card out in a timely manner. We don't know who it's from, since it was shipped from the store.
What's the right ettiquette in this situation?
